X-ray powder diffraction from solid deuterium was observed under high pressure and low temperature at SPring-8. Three diffraction lines were obtained, and they are assigned to the 100, 002 and 101 lines of the hcp lattice. The center of each deuterium molecule is still on the hcp lattice in phase II.
